the anterior extremities only, special modifications of the 

 pelvic arch and limbs, and muscles thereto attached, whereby 

 the erect position is maintained, the highest development of 

 brain, and, no muzzle. 



II. In the Order QUADRUMANA, the hand (innermost 

 digit opposable) is present on the posterior extremities ; and 

 the muzzle is more or less elongated. Three well-defined 

 Groups are comprised in this " Order,^' viz, : 

 1. Catarrhina 2. Platyrrhina. 3. Strepsirrhina 



or Simiadae. or Lemuridae. 



which are divided into two 



Sub-orders : 

 First, SimiaDtE, or Monkeys, including the two first groups. 

 Second, Lemurid^, synonymous with the third group. 



The Catarrhina have the nostrils oblique and approximated 

 below, and opening above and behind the muzzle. They are 

 restricted to the Old "World. This Sub-order includes the 

 Anthropomorphous (tail-less) Apes, Baboons, &c. 



The Platyrrhina have the nostrils simple, sub-terminal, and 

 wide apart; and the tail generally prehensile. They are 

 peculiar to South America, 



The Strepsirrhina have curved or twisted terminal nostrils. 

 They are confined to Africa, Madagascar, and India. In this 

 Sub-Order, the Cheiromys (Aye- Aye), is included, which was 

 classified by Cuvier among the Eodentia. 



III. Among the INSECTIYORA, all of which have 

 molar teeth, bristled with cusps, the Galeopithecidce find a 

 place : these have by various authors been assigned to the 

 Cheiroptera (Cuvier), or to the Lemuridae of the Quadrumana. 

 The latest authorities, however. Professors Owen and Huxley, 

 classify them as here given. The other members of this 

 Order are the ErinaceidcB, which have the body covered with 

 prickles instead of hairs ; the Soricidce, with close fur, pointed 

 muzzle and scaly tail ; and the TalpidcBy which have amazingly 

 powerful fore-feet, and lack the organ of vision.
